This inwentiony relates to improvementsvin'A Y building materiali f Y The present invention Yhasfor its ob]ects, amongothers, to provide a` covering orvkey v i base to beused for walls of buildingsntowhich cement, concrete, or other plastic material may bedirectly applied, and whichshall be strong, durable Vand rof'general; utility. Y i

My improvedw building material is well '10 adapted for outsidewalls as well as partition walls, inside walls, a reinforce -for concrete, y floors,'and infact forfall purposes Where it may be desired to employ a fire-proof, waterproof, strong base for a substitute for Wood or 15 metal lathing, sheathing, as a base for con- Y creteffloor's, and. many other purposes.V It will save the necessity ofthick and heavy plastering, can be easily and quickly installed y and applied, will: afford the maximum of l f` strength, withv minimum weight, anditwill- .prevent buckling or springing of the wall' and at the" same time insures against bucklingv at right angles. Itfwill save thecracks so often found atthe corners ofv a room as itsluse will insure strong end pressure where secured at an angle.

Other objects and advantages of the inj vention will hereinafter appear, vand the .Y

novel features thereofvwill be specifically v`declearly illustrated in the accompanying drawings, which, with the numerals of reference r i marked thereon, form a part of this specificaf #335r tion and inwhich i c f v Figure lis a fragmentaryperspective view.A

- Referringto the drawings: 'v r41 designates va backing, or foundation, meinportio'n of my improved 'building mateber lof metal, made without perforations, slits Lor "openings, this member being designed to be secured, in any-'suitable manner, directly rto"thestudding or other support 2,in Figure 4, and this member is, byany suitable means, given the 'Zigfzfag shape seen in all of the views of the drawings, It isto be noted that this member fl is vnot corrugated, that is, it v.is

formedfwith Zig-Zagback and front faces Ias seen at 2fand 3,'the apices4 and 5 being oomas' seen best in Figure 5. I Vhave. found that this'provides a better jointor depression for thev-holding 'ofthe cement or other cementitious material that lmay be usedrin connec- To give greater strength tor-the material I- providemem'bers 6, in the present instance ishown.: as 'wires' of suli'cient diameter, the

said membersy being .securely aiiXed to the lapices o-f the meinberlin suitable manner as byelectric welding as shown at 7. I deeml it essential that thesefstrengt-hening vmembers .beattachedinsuch va manner as to avoid -the 'Y :presence of perforations or slits for the reception offthe wires andv that the Wires be paratively sharp, substantially right'anglesfiXedly-attached in position onthe memberL lasthis insuresfgreater strengthand rigidity and hence increasesthe endwise resistance to bucklev in use, as well as keeping the material -'in its original' condition so as not to be in .any wise deformed in handlin Although' my material avoids the necessity of the employment of felt, tarpaper or'the like, .itis to be understoodrthatsuchrmay be employed in connection therewthwhenever deemed advisable. j" -l l Ifdispense with the employment of wood 1 or metal lathingY-,or th-e like, and in the useof lmy'mat'erial I combine the various processes of stiifening, weather-proofing and lathing, all Y .inthe onefo'peration. 1 f

. For the outside of a building, in case stucco or other plasticsurface is. desiredI I place .the

studding in position, then a complete layer of my building material is placed in position, securing the ends thereof to the studding 2, or other support, by any suitable means as by nails or the like 8, see Figure 4L, the material I being laid with the wired apices of the material toward the outside, then .I Vplace thereon the coating of cementitious material as seen atV forced through the foundation upon Which it' is placed, as is the usual result, less plaster.

will be required and the cling is much stronger. The plastic material is not only better retained in the Zig-Zag depressions, but the rods afford a better hold therefor, with the result that cracking of the plaster is entirely prevented and a better job is assured. Furthermore, it requires less time with a much better and evenerV surface 'as a result'. `Furthermore, I eliminate cracking at the corners as well as elsewhere, there being no shrinkage resulting, and the resistance to end pressure-is greatly increased. l Y

I provide a sealed wall impervious to wind, heat, cold, water, dampness and the like and dispense with the necessity of clinging of the plastic Vmass behind the foundation upon which the plastic material isplaced.

In the use of the material for inside Walls, for partitions where both sides are to be plastered, I employ brace members as wires l0, upon both sides of the foundation member l as seen in Figure 3, securely attached as by electric welding or the like, as seen at ll inV lFigure 3, one set upon each side of theV foundation material l, as shown, and then place come evident to others skilled in the arts, to obtain part or all of the benefits of my'inv-ention Without copying the structure shown,y

points forca reinforcing means, and members Y disposed at substantially right angles to said cavities and securedto the apices of both sides of the wallsof such cavities. V

' 2. As an improved articleofmanufacture, a metallic building member 1 of sheet lmetal corrugated and formed upon itsropposite faces with alternatingrangled formations, andstrengthening and connecting members upon oppositeY faces thereof and secured to the apices of such angled portions. l

upon each side thereof the requisite coating of plastic material of whatever nature may be desired. This makes a very strong, not liable to buckle upon either side, form of wall'Qin which the plastic material will be securely retained within the substantially right-angled cavities in the member 1. This will be readily understood upon reference to Figure 3.

V Such a wall has great strength and capacity for preventingv shrinkage or warping, or cracking at the corners, so that less uprights are required than where wood or metal lath ing is employed upon opposite sides of uprights.

The one-surface side only of the member l being wired. and plastered is particularly qadapted for use as inside walls, and interior application such as for brick work, for brick veneered walls, 'or for stone outside surface,

' roofs and the like. The two-surfaced side nishing of the body is more particularly adapt-y ed .for use on outside walls, partition walls, and the like.

In view of my invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless be-`
